Children in low-mid income countries, and First Nations children in high-income countries, experience disproportionately high rates of Streptococcus pneumoniae and Haemophilus influenzae infections and diseases including pneumonia and otitis media.
Pneumonia is the leading cause of death in young children globally and is prevalent in the Papua New Guinea highlands. We investigated clinical predictors of hypoxic pneumonia to inform local treatment guidelines in this resource-limited setting.
One third of children require repeat ventilation tube insertion (VTI) for otitis media. Disease recurrence is associated with persistent middle ear bacterial biofilms. With demonstration that Dornase alfa (a DNase) disrupts middle ear effusion biofilms ex vivo, we identified potential for this as an anti-biofilm therapy to prevent repeat VTI. First, safety and tolerability needed to be measured.
Chronic wet cough for longer than 4 weeks is a hallmark of chronic suppurative lung diseases, including protracted bacterial bronchitis, and bronchiectasis in children. Severe lower respiratory infection early in life is a major risk factor of PBB and paediatric bronchiectasis.
Otitis media (OM), middle ear infection, represents a significant burden on children, their families, and the healthcare system. OM is the major cause of hearing loss in children and if left untreated in children who suffer chronic and recurrent forms of OM, this disease can have serious life-long sequelae.
The Bacterial Respiratory Infectious Disease Group (BRIDG) has a major focus ear and lung disease involving Streptococcus pneumoniae and Haemophilus influenzae.

Coronavirus-2019 (COVID-19) vaccination in Australia commenced in February 2021. The first vaccines recommended for use were AZD1222 and BNT162b2, both delivered as a two-dose primary schedule. In the absence of sustained immunity following immunisation, recommendations for booster vaccination have followed. It is likely that periodic boosting will be necessary for at least some Australians, but it is unknown what the optimal booster vaccines and schedules are or for whom vaccination should be recommended.
PICOBOO is a randomised, adaptive trial evaluating the immunogenicity, reactogenicity, and safety of COVID-19 booster strategies. We report data for second boosters among individuals 50-<70 years old primed with AZD1222 (50-<70y-AZD1222) until Day 84.
